SHIELD FOB.- MOIOR RADIATORS.

Specification of Letters Patent. Patented June 27, 1922 Applicationfiled March 6, 1920. Serial No. 363,758.

useful Shield for Motor Radiators; and we do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, in which like numerals refer tolike parts.

The chief object of this invention is to provide improved damper meansfor regulating the amount of air passing through a motor radiator. Thisinvention in particular is an im rovement upon the device shown inPatent 0. 1,277,589.

Another feature of the invention consists of simplifying andstrengthening the parts comprising the invention, whereby the cost ofmanufacturing the same will be greatly reduced.

A further feature of the invention consists in constructing the partsthereof in such a manner that the invention may be readily attached to aradiator of a water cooled internal combustion engine found upon motorcars and the like, said attaching means securing said shell to theradiator in an improved manner.

A further feature of the invention consists in constructing the same sothat the invention may be adjustably secured to all cars provided withflat front radiators.

The full nature of this invention will be understood from theaccompanying drawings and the following description and claim.

In'the drawings Fig. 1 is an eleyational front view of a motor vehicleradiator to which the invention has been attached. Fig. 2 is a verticalsectional View of the same taken on the line 2-2 of Fig. 1. Fig. 3 is arear view of the radiator shield. Fig. 4 is a view illustrating thegeneral method of attaching the radiator shield to any square frontradiator. Fig. 5. is an enlarged sectional view showing in detail themethod of securing the shield to the radiator. Fig. 6

is an end view of the securing means shownhicle by which the dam erconstruction of the shield may be contro led.

In the drawings 10 indicates the cu stomary radiator provided with theusual fins 11 and water tubes 12. A shield plate 13 1s adapted to bepositioned forwardly of said radiator and to be secured thereto in animproved manner, particularly illustrated in Figs. 4:, 5 and 6. Hereinthe shield plate 13 is shown formed with socket depressions l 14, thesame seating suitable bolt means '15 wh ch are adapted to extendthrougli'Z-said radiator adjacent the tubes thereof and be-- tween thefins, as shown. Upon the other end of said bolt is positioned areenforcing plate 16, said plate being rovided with inwardly turnedflanged e ges 17, the same adapted to be positioned adjacent the usualhorizontal fins 11. In this manner the plate 16, substantially abutsseveral of the fin edges, as shown particularly in Fig. 5, whichprovides an improved and substantial bearing or supporting base. Thereenforcing plate 16 is also-provided with a plurality of outwardlyprojecting flan es 18,.the same being in spaced relation with each otherso as to engage and grip the retaining nut 19 and hold the samenon-rotatably in position upon the rod 15, as shown. From the foregoingit will be understood that the plate 13 may be rigidly-secured to anyradiator without danger of becoming loose or bending the fins of theradiator.

The damper arrangement provided by said shield 13 is formed of but fewparts and those of simple construction, to wit, the

- shield plate 13 is provided with a plurality shown connected bysuitable connecting portions 25 formed integral therewith an the plate22. In the drawings said connecting portions 25 are positionedsubstantially midway between the top and bottom of the damper plate andare substantially in alignment with each other. As shown in Flgs. 1 and2 the s ot 2 an the longitudinal spacing portion 24 of the damper plate22 are adapted to register with the longitudinal slots 20 of "the shield13 to respectively position the damper in the open positlon or in theclosed position.

The damper plate. 22 is herein shown provided with a plurality oftransversely extending guide slots 26, the same receiving and seatingsuitable guide pins 27 supported upon the shield plate 13. Integral withthe plate 22 is a transversely extending portion 28, the same being inalignment with the transverse connecting portions 25. Su;it-, able meansare provided for reciprocating the damper plate 23 upon the guide pins27 from the extreme closed position illustrated in Fig. 1 to the extremeopen position, or to any intermediate position desired, saidreciprocating means, as shown clearly in Figs. 1, 2, 3 and 7, comprisinga lever handle 29 pivotally mounted in the dash board of the motorvehicle and having a shaft portion 31 extending therethrough, asillustrated. Suitably secured upon the dash and adjacent the lever 29,and cooperating therewith, are a pair of stop pins 32 which indicate theextreme open and closed positions of said damper construction and limitthe movement of said lever handle. Positioned above said stop pins andsubstantially concentric with the pivotal support of the lever 29 is anarcuate rack 33 provided with a plurality of substantially radialnotches 34 in which the free and coiled end 35 of the lever 29 isadapted to be seated. As shown in Fig. 7, a suitable plate 36 isprovided with the pivot support 37, and the arcuate rack 33 and issecured to the dash 30 by means of stop pins 32. It will also be notedfrom Fig. 2 that the handle 29, the latching portion 35 and the shaftportion 31 are composed of a single rod member, and as formed theortions 29 and 35 form a spring handle whic is so bentcas to force thefree end 35 into frictional engagement with the arcuate rack and seatsthe end in one of the notches 34. A rock shaft 38 is suitably connectedto the )ivot shaft 31 by means of the connecting p ate 39, as shown.

Positioned upon the front of the shield plate 13 and suitably securedthereby by means of rivets or bolts 40, is a triangular ca portion 41,said cap covering a triangu ar opening 42 so as to provide a recess.Upon t e opposite side of the shield plate a cross member 43 is suitablysecured by means of the bolts or rivets 40, as shown. The cross member43 provides a bearing at the apex of the triangular opening for the rockshaft 38, as shown, and the same extends through said bearing and uponits end there is secured a link 44, the same being connected at itsopposite end with the transverse actuatin portion 28. From the foreoingit will %6 understood that when the ever 29 is turned, the rock shaft 38transmits the motion thereof to the actuating portion 28 whichreciprocates the plate 22 to open close or adjust the position of saidlongitudinal openings to regulate the amount of air passing through theradiator.

The invention claimed is: In a radiator shield construction a shieldplate provided with a plurality of parallel longitudinal openings, adamper plate provided-with similar openings, the latter openings beinregistrable with the former openings, sai one edge thereof, a barsecured to the other side of said shield plate adjacent the recess, arocking link pivotally supported in said recess upon said bar, a rockshaft for rocking said link, and means for rocking said shaft.

In witness whereof, we have hereunto affixed our signatures.
